To all whom it may concern:

Be it known that we, HARVEY B. Gun and HARRY R. ROBERTS, citizens of theUnited States, residing at Sheridan, in the county of Sheridan and Stateof -Wyoming, have invented certain new and useful Improvements inAir-Shutters for Automobile-Radiators; and we do declare the followingto be a full, clear, and exact description of the. invention, such aswill .enable othersskilled in the art to which it appertains to make anduse the same.

Our invention relates broadly to improvements in automatic accessoriesand more particularly to a shutter for attachment to automobileradiators for varying the amount of air passing through the same andthus controlling the temperature of the water cooled by such radiators,as well as the temperature of the motor.

The object of the invention is to provide a device of this class whichalthough being of very simple and comparatively inexpensiveconstruction, will be highly efficient in operation and will possess anumber of advantageous features.

With this object in view, the invention resides in certain novelfeatures of construction and in unique combinations of parts hereinafterdescribed and claimed.

In describing the invention, we shall refer to the accompanying drawingswherein like reference characters designate corresponding partsthroughout the several views and wherein:

Figure 1 is a side elevation of a portio of an automobile showing theapplication of the invention to the radiator thereof; Fig. 2 is a frontelevation of the shutter and the radiator to which the same is applied;Fig. 3 is a vertical section taken along the plane indicated by the line33 of Fig. 2; Fig. 4: is a perspective view of the'rear attaching plateto be described; Fig. 5 is a perspective of the shutter actuating ring";

AIR-SHUTTLE FOR AITTOMOTBILE-DIATORS.

is allowed to pass for the purpose of cooling trance of too much coldair into the hood and for entirely closing the front of the radiatoragainst the entrance of such air when necessary. Some of these deviceshave proved to be rather efficient, while others have never come intopractical use on account of the fact that the desired ends cannot beattained thereby. It is therefore our intention by the present inventionto overcome the diflicultics' heretofore encountered and to thus providea shutter which will possess a number of highly advantageous featuresalthough being of very simple and inexpensive construction. To this end,the construction shown in conjunction with the radiator R is provided.

Disposed in contact with the front side of the radiator, is a rearrectangular attaching plate'l which terminates a slight distance abovethe openwork of said radiator and which rests upon the bar B previouslydescribed. Either secured to or formed integrally with the upper edge ofthe plate 1, is an ear 2 which is preferably notched and receives in itsnotch a bearing 3 through which and through the ear a bolt of the like 4is passed. The bearing 3 is shown in the present application as formedintegrally with a fork 6 straddling the filling nipple N of the radiatorR, a clamping plate 7 being forced into contact with the rear side ofsaid nipple by'nuts 8 threaded on the ends of the forkfi. By the detailof construction just described, it will be evident that the plate 1 maybe secured to practically any type of automobile, provided the clamp andparts associated therewith be constructed of proper proportions.

Spaced an appropriate I distance in advance of the'rear attaching plate1 is the front attaching plate 9, the two plates being spaced bysubstantially triangular plates 10 interposed between the four cornersthereof, vbolts of the like 11 bein then passed through said cornersand' t i-cu'gfr' the plates 10 therebetween. The lower corners of thefront attaching plate's'9' are provided with angle iron brackets or thelike" 12 resting on and secured to .an attaching bar 13 whose ends arebent downwardly an then extended laterally to provide feet 14 resting onand bolted or otherwise secured tothe'barsB; It will. be evidentthatsuchadditional means 'of attaching the inven-' tion to an automobile may belikewise applied to use in connection-with practically 15 any makeof'machine As clearly disclosed in Figs. 4 and-7, the rear platel andthefront plate 9 are provided with circular openings 15 whereby theybecome'in' efi'ect rings, and in addition to the openings15, the frontplate '9 is'proa vided with an arcuate slot 16' disposed 'con centricwith the surrounding wallxof' its pening 15.

. The front :and rear plates previously de- .25 scribed and the spacingplates 10 at the corn'ers thereo'fgconstitute a rectangular casingwithin which'the shutter and'tlie actuatingproject removablyinto anannular series of openings with which the rear attaching plate '1 isprovided. The opposite ends'of said plates, however, are providedwith-"forwardly extending studs 19" which are re- 40 ceived by radiallydisposed slots 20:opening through the inner edge of a: flat slnrtter'a'c Thus it" will eviden t' tuating-rin'g 21. that when the ring'isrotated im the proper direction, the several overlapping plates'17" willbe rocked around the studslB tolbring their inner edges toward thecenter of the openings 15 as disclosed in Fig. 2, whereas movementofsaid ring in the oppositeidirection will again dispose the severalplates l7 adjacent the edges'ofsaid-openings. For

sofactuating'the ring '21, the same i'spro vi'ded with a forwardlyprojecting" handle 22 having on its rear portion acoiler'f spring 23normally forcing-a washer 2 fforwardly,

I the front end of said-handle bein projected through the slot 16. andequipp 5 with any preferred type of knob 25, said-knob being preferablyin the form of a nut.

The spring 23' serves to forcea portion of the ring 21 toward the rearplate 1, thus frictionally binding the severaiwarcuate shutter plates 17between these parts-and notonly preventing rattling, but retaining suchplates in their adjusted-position. It,

willlbe evident; however, that the spring equalized, thereby producingthe desirable in question does 1 not exert its tension hrees zq t e rumf r ngepi the ring it being theiefdre expedient to provide additionalspring pressedanti-ratthng and brake means for frictionall'y retainingthe remaining of ,the plates 17 in adjusted positions and for preventingrattling of the several parts. To this end, a split brake ring 26 isprovided, said ring being disposed in contact with the front side oftheshutter actuating ring 21' throughout the greater part of thecircumference thereof, although the ends of said ring terminate at p0ints'; disposed adjacent the ends of the slots 16, thus allowing theproper amount of movement on the part of the handle 21 and therebyallowing the ring 21 to have such movement, during whichthe spring 23actuates in the mannerabove set forth j-while additional springs 23which are interposed between the front plate 9 and the brake ring 26exert their tension to force said ring rearwardly against the ring 21,thus exerting a braking action thereon as well as forcing the same intosuchforcible contact with the plates 17 as to positively preventrattling thereof.

In order to lock the brake ring 26 against rotation with the ring 21 andthereby prev vent cramping of'the springs 23, said brake ring isprovided 'witha plurality of forwardly extending pins 27 which projectthrough the springs 23 and through openings in the front plate 9, itbeing thus evident that in addition to the other advantages derived bythe use of the pins 27, they retain' the springs 23 in their relativepositions.

By the provision of the brake ring and the springs 23*. forcing the"same toward the rin 21', thereby shifting this ring toward the plates17, and by the provision of the spring 23 which'likewise shifts the ring21 towardthe plates 17, the frictional contact existing between thecontacting parts is results, above set forth.

When the invention is applied to use, it is simply necessary to shiftthe knob 25 in one direction or the other inrespect to the" slot 16, tobring-the inner edges of the several plates 17 toward each other,thereby forming a comparatively small opening at the center of thedevice, or to cause said edges to reeede from each other to increase thesize of the opening. After such adjustment has been mad e'to accuratelycontrol the temperature within the hood H, the brakering 26 and thesprings 23' and 23* cooperate to prevent shifting and rattling of theseveral movable partsof the shutter as the machine is being. driven.

- From the foregoing, description, taken in connection with theaccompanying drawings;- it .willbe evident that although compa'rativelysimple construction has been pro- 130 vided for the attainment of thedesired end, the invention will be extremely eflicient in operation.

In the aforesaid drawings, certain specific I details of constructionare shown for accom- I plishing probably the best results, and in thepreceding such details have been described, but it will be evident thatwe need not be limited thereto otherwise than tothe extent to which theappended claims limit us.

We claim: .1. In a shutter, the combination with a fixed plate having anopening, a plurality of arcuate shutter plates pivoted at one end atpoints spaced around said opening, and a shutter actuating ring havingpivotal and radially slidable connections with the other ends of said"plates; of spring means forcing the actuating rin'g'toward the shutterplates.

4. In combination, a fixed plate having an at opening, a plurality ofarcuate overlapped shutter plates pivoted at one end to said. plate atpoints disposed around the openmg thereon, a shutter actuating ringdis-"4 posed in contact with the sides of the shutan ter plates remotefrom the fixed plate, piv: otal and radially slidable connectionsbetween the other ends of said shutter plates and the shutter actuatingring, a handle projecting from said actuating ring away from 5 5 thefixed plate, a split brake ring disposed in contact with the side of theshutter actuating ring remote from the shutter plates, pins projectingfrom said brake rin in the direction of thehandle,anadditional'xedplatehaving W openings receiving said pins and an arcuate slotthrough which the handle projects, a coiled spring surrounding thehandle and interposed between the additional plate and the shutteractuating ring, and additional coiled springs surrounding the aforesaidpins and interposed between the brake ring and said additional fixedplate.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
